Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To accurately decide the quality of the defect of a photomask by obtaining light intensity distribution in the case of exposing and transferring a mask pattern to a wafer from image data on a pattern area including a defect correcting part. SOLUTION: A mask pattern image observed by an image observation means 7 is inputted in an image data conversion means 8, and converted into pattern data for light intensity simulation. By performing simulation calculation in a light intensity simulation means 15 by using the data for light intensity simulation converted and generated by the means 8, a light intensity distribution value is obtained. A series of procedure to perform the simulation processing of the image data is controlled by a control processor 14. The light intensity simulation is to obtain exposure distribution, that is, the light intensity distribution on the wafer in the case of attaching the photomask on an aligner and exposing and transferring the photomask on the wafer by the simulation calculation to which an optical system model is applied.

Title: Image forming device
Inventor: WATANABE JUNJI
IPC: G03G15/043
Filed: 1985-07-15
Abstract: PURPOSE:To copy an original image while erasing its optional part without increasing a device shape in size by moving a lens block for variable power except to an enlargement position when the erasure range of the original is specified. CONSTITUTION:The latest copying machines tend to move mirrors 6 and 7 to very nearby the lens block 8 for the variable power at an unmagnification position when scanning an original platen 2 at the maximum for size reduction. Therefore, when the erasure range is specified within the maximum erasure range Emax by using a spot light source 131, there may be trouble in moving the spot light source 131 if the lens block 8 for the variable power is at the enlargement position. For the purpose, when the erasure range is specified, the lens block 8 is moved except to the enlargement position.

Abstract: PURPOSE:To provide the filter cloth which can accelerate the removability of cake by using twisted yarn, which is formed by using elastic yarn of polyurethane as core yarn and coating the surface of this core yarn with multifilament bulky finished yarn of polyester, etc., for both or either of warp and weft. CONSTITUTION:This filter cloth for a filter press is constituted by using the twisted yarn, which is formed by using the elastic yarn of the polyurethane as the core yarn (a) and coating the surface of this core yarn with the multifilament bulky finished yarn (b) of the polyester, polyamide and polypropylene for both or either of the warp and the weft. The filter cloth is released from the extended state and tends to restore shrinkage when a filter frame is opened after pressure filtration with a filter press according to such filter cloth. The bulky finished yarn (b) on the filter cloth surface absorbs liquid-components while the yarn is crimped by the shrinkage of the core yarn (a) at this time and the surface of the filter cloth in contact with the cake is wetted with the filtrate and the contact force with the cake is lowered. The cake and the surface of the filter cloth are slid from each other by the elongation effect acted on the filter cloth, by which the peeling of the cake is accelerated.
